    Hi falko,
    of course 192.168.253.52 is free in my entwork
    i typed exactly the commands found in the how-to
    i don't understand what you mean (execuse me, i'm not fluent in english) :)

    i tried several templates (debian, centos, fedora ..) but i still get the same problem as describe before.
    I can give you more details if needed.
    Thanks in advance.

    Which error do you get, if you execute this command on the shell:

    arpsend -c 1 -w 1 -D -e 192.168.253.52 eth0

    Do i need a special configuration on the machine specified as "name server" during the configuration ? Bind, Windows AD or anything else ?

    Are you absolutely sure that 192.168.253.52 isn't already in use?

    yes, it is 100% sure
    that's why this problem looks strange to me :mad:

    What's the output of
    Code:
    ifconfig
    on the main machine? What's the output of
    Code:
    ping -c4 192.168.253.52
    on the main machine?

    This means that 192.168.253.52 is already in use in your network.

    OpenVZ Pb (vmware)

    Hello,
    i get exactly the same problem in a vmware. But i've already configured one in the same way and it works fine.

    arpsend: can't get iface 'eth0:' address : Cannot assign requested address
    vps-net_add WARNING: arpsend -c 1 -w 1 -D -e 192.168.1.44 eth0: FAILED
    etc....

    The ip 192.168.1.44 is free (i'm sure) .

    The command arpsend -c 1 -w 1 -D -e 192.168.1.44 eth0 return no errors.

    eth0 is already in use (with the IP address 192.168.1.24)... :confused:

    Re

    Yes of course. It's the ip of the "master" .

    master => 192.168.1.24

    vserver1 => 192.168.1.44

    etc...
    And i repeat : this config works perfectly on another vmware with the same distrib (debian-3.1 stable).

    Sample config ok/nok

    Hello,

    I've put here http://xoopmenier.dynalias.net/xoops/docext/vservers/details.htm
    a config which run perfects.

    We see this :
    on the master ifconfig outputs :
    .....
    venet0 Lien encap:UNSPEC HWaddr 00-00-FF-00-00-00-00-00-00-00-00-00-00-00-00-00
    ....

    in the vps ifconfig outputs :
    ...
    venet0 Link encap:UNSPEC HWaddr FF-BF-A8-F6-FF-BF-38-93-00-00-00-00-00-00-00-00
    ...
    venet0:0 Link encap:UNSPEC HWaddr FF-BF-A8-F6-FF-BF-1C-F7-00-00-00-00-00-00-00-00
    ....

    Now on a machine which fails to start the vps :

    ifconfig on the master :
    ...
    venet0 Lien encap:UNSPEC HWaddr 00-00-FF-00-00-00-00-00-00-00-00-00-00-00-00-00
    ....

    ifconfig in the vps :
    ...
    venet0 Link encap:UNSPEC HWaddr 00-00-FF-00-00-00-00-00-00-00-00-00-00-00-00-00
    ....
    venet0:0 Link encap:UNSPEC HWaddr 00-00-FF-FF-FF-FF-00-00-00-00-00-00-00-00-00-00
    ....

    We see that HWaddr of venet0 is the same (master/vps) on the broken config. Hope this helps network's gurus to solve our problem...

    Partially solved

    Finally i destroy the virtual machine and reinstall it and that works but i didn't like this behavior and i migrate to linux-vserver.

    Thanks for your help.
